Halococcus hamelinensis is a halophilic archaeon isolated from the stromatolites in Australia. These living stromatolites are exposed to extreme conditions of salinity, desiccation and UV radiation.^[3]H. hamelinensis is able to survive high UVC radiation doses due to the presence of the bacteria-like nucleotide excision repair genes uvrA, uvrB and uvrC (that encode the UvrABC endonuclease) as well as the photolyase phr2 gene.^[3] The uvrA, uvrB and uvrC genes are upregulated upon UVC irradiation.^[3]
